Displ lateral mass fx 1st cervcal vert, 7thG

This code signifies a fracture of the lateral mass of the C1 vertebra, which is out of its normal anatomical alignment. The patient is in a phase of recovery where the fracture is not healing at the expected rate. This indicates ongoing medical management for a delayed union of the fracture.

Apply this code when documenting follow-up care for a C1 lateral mass fracture that was initially displaced and is now exhibiting delayed healing. This would be used during subsequent visits after the initial treatment, where the physician notes that the fracture is not progressing towards union as anticipated.

• Ensure documentation explicitly states "delayed healing" or similar terminology for the fracture.
• Verify the fracture is specifically of the lateral mass of the first cervical vertebra and was initially displaced.
• This code is for subsequent encounters, not the initial treatment of the fracture.
